If you’re new to DIY synthesizer building, you might’ve run into this issue: you just set up your first VCO on a breadboard, spent a good while troubleshooting the stubborn thing – and then you realize you have nothing to actually control it with. OR if you already have a decent modular setup, but still haven’t found a simple, hands-on sequencer – here’s a compact, yet versatile 5 step sequencer with adjustable sequence length, per step gate status, and output range! It works both from an internal and external clock and has reset input for more complex sequences if several sequencers are chained up. It works also as a waveshaper when clocked at the audio rate.
We – Erica Synths and Moritz Klein – have developed a series of educational DIY kits under the brand name mki x es.EDU with one specific goal in mind: to teach people with little-to-no prior experience how to design analog synthesizer circuits from scratch. What you’ll find in the box is not simply meant to be soldered together and then disappear in your rack. Instead, we want to take you through the circuit design process step by step, explaining every choice we’ve made and how it impacts the finished module.
In total, we have developed 9 kits to build a fully-featured modular monosynth: a sequencer, a VCO, a wavefolder, a noise/S&H module, a mixer, a VCF, an Envelope generator, a dual VCA, and an output stereo mixer with a headphone amplifier. Additionally, an affordable eurorack case with a DIY PSU will also be available. While these kits are easy to build, we did not compromise on design and functionality. We will launch one kit every 4-6 weeks. For each kit, there is an extensive user manual (40+ pages; can be downloaded separately) that will dive deep into not only the electronics behind each circuit but also the fundamental principles of sound synthesis. We hope that the mki x es.EDU project will inspire future engineers and will contribute to the ever-growing diversity of electronic music technology.
